Manifolds/change over regulator

Gas Cylinder Changeover manifold: A two-stage gas cylinder changeover manifold automatically switches between two sources. Two first stage regulators arrange the switch over from a primary source that reached the set point (low) pressure to secondary source. This change over pressure is a fixed pressure in most cases. At a second line regulator the outlet pressure can be set. This construction allows a constant outlet pressure when inlet pressure changes, also when empty gas bottles as sources have to be changed for full ones.
